Conseguir Mostrar nombre de PackageID

Question

Mirando a través de la fuente de la aplicación Wix Estándar programa previo, parece que cada paquete tiene un DisplayName propiedad:

pPackage->sczDisplayName 

Sin embargo, la DLL BootstrapperCore que se utiliza en la configuración de WiX proyecto no tiene esta propiedad. ¿Hay alguna forma de extraer esta propiedad de los paquetes en el código administrado?

Answer 2

El archivo BootstrapperApplicationData.xml que se genera durante el proceso de compilación se coloca junto a su BA .dll. Puede cargar ese archivo XML para obtener mucha información sobre el paquete y los paquetes en el paquete.

Para cargar el BootstrapperApplicationData.xml en el código nativo, utilice el método BalManifestLoad() en balutil.lib que se proporciona con el conjunto de herramientas de WiX. Puede ver el código en src\ext\BalExtension\balutil\balutil.cpp. Luego puede usar BalInfoParseFromXml() también en balutil.lib para analizar el archivo XML en un conjunto de estructuras útiles. Puede ver el código en src\ext\BalExtension\balutil\balinfo.cpp.
